Although sickle cell disease is inherited and present at birth, symptoms usually don't occur until after 4 months of age. (health.am)
The goal of treatment is to manage and control symptoms, and to limit the number of crises. (medlineplus.gov)
Symptoms of anemia - like fatigue or shortness of breath - happen because your organs aren't getting what they need to work the way they should. (webmd.com)
At a certain point, as your blood cells decrease, symptoms often develop. (webmd.com)
Transfusion should be provided based on symptoms of anemia and not hemoglobin levels. (kevinmd.com)
Children may experience a broad range of sickle cell symptoms and disease severity. (childrenshospital.org)
In addition to these symptoms one of the typical symptom experienced by patients called Sickle Cell Crisis. (globalgiving.org)

The drugs are called HDAC inhibitors, and the investigators have early evidence one called panobinostat can reactivate after birth the gene that produces fetal hemoglobin, which cannot sickle, says Abdullah Kutlar, MD, director of the Center for Blood Disorders at the Medical College of Georgia and Augusta University Health.
